Abstract: A vacuum switch having a fixed stationary and moveable contact that functions very much like a conventional vacuum circuit interrupter. In addition, an annular stationary contact is positioned on the opposite side of the moveable contact from the first mentioned stationary contact with the drive rod of the moveable contact slidable within the annular opening of the additional stationary contact. The moveable contact travels between three positions. The first position is in electrical communication with the first mentioned stationary contact, the second position is an intermediate position that opens the circuit, and the third position places the moveable contact in electrical communication with the annular stationary contact. Preferably, one of the stationary contacts is grounded and the moveable contact is connected to the load, so that the switch either connects the power line to the load, opens the circuit in the intermediate position, or grounds the load to facilitate maintenance.
